Hello! I checked some threads with the same title, but they were all about a noise that they heard! I have another problem:
I don't heard the noise, I see it. Sometimes my screen goes all fuzzy, but it's only for a while, then comesback to normal.
I already check the temp of the GPU but it seems to be normal: in idle is about +40c, and when I play is about +50c. It never reach too high temps like 70.
I have a HD6950 2gb oc edition (without oc), my PSU is 650w (Sentey), and the monitor's native res is 1360x768 (Samsung Syncmaster 933), and I use the native res for all games without AA nor any weird thing.
So, what could it be? Some driver is malfunctioning? The card isn't old, but the monitor is at least 2 years..
PS: I learnt english from games, so don't expect too much..
